Golden Gate Canyon is a State Park and a $7 (2010) fee is required for entrance. Self serve kiosks exist throughout the park. Annual passes can be purchased for $60.
Climb the Squaw's backside, starting at the little notch on the east end and spiraling around the north. Cut hard right just off the notch, and follow fun steps to a ledge below overhangs. Climb very steeply, with good pro, until you can step right onto a good stance below final overhang. Find as much pro as you can, step right again, pull the bulge, and mantel up to the top. If you do it the way we did, you'll finish right at the summit chains.
Standard rack, extra slings. Small wires are useful at the top.
